MACHINE FOR COVERING WOOD WITH METAL.-

SPEGIFICATION forming part of Letters Patent NO. 625,531, dated May 23, 1899.

Application filed September 19,1898. Serial No. 691,291. (No model.)

To alt whom it may concern.-

Be it known that I,WILLIAM P. APPLEYARD, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Machines for Covering W'ood with Metal; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and'exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a plan view of a machine constructed in accordance with my invention; Fig. 2, a side view of the same; Fig. 3, a partial longitudinal section, broken away to more clearly indicate the construction of the machine; Fig. 4, a transverse sectional view on the line a b of Fig. 1; Fig. 5, a broken transverse sectional view of the bed and guideways thereon; Fig. 6, a broken view of the primary roll, illustrating the first step in the covering operation; Fig. 7, a perspective View of one end of a strip of wood and a strip of metal thereon, illustrating the position of the strip preparatory to the bending operation; Fig. 8, a perspective view of the end of a strip of wood the surface of which is covered with metal.

This invention relates to an improvement in machines for covering strips of wood with metal, and particularly to machines for covering strips of sheathing in which the metal covers one face of the strip and extends partially around the tongue and into the groove of the strip.

In metal-covered strips it is very important that the metal should be tightly drawn over the strip; and the object of this invention is to produce a machine in which the strip and the fiat metal may be fed together and the metal automatically folded over the tongue and into the groove and so as to hug the same closely; and it consists in certain details of construction and combinations of parts, as will be hereinafter described, and particularly recited in the claims.

The machine consists of a bed A and a table B at one end and a table B at the opposite end. Between these tables and in opposite sides of the bed are mounted bearingblocks 0, which form bearings for the various parts of the mechanism, as will hereiir after appear. In the upper portion of these bearing-blocks and so as to stand above the table is a primary forming-roller D, corresponding to the upper surface of the strip to be covered. This rolleris mounted onashaft E, held in bearings F F in the bearing-block C. At one end of this shaft is a large gearwheel G, which is driven by asmaller gear H on a shaft l, suitably mounted and driven by a pulley J. On thersame driving-shaft is a loose pulley J, as is usual in belt-driven machines. On the opposite end of the shaft E is a gear K, which meshes into a similar gear K on a'shaft L, parallel with but below the shaft E. On this shaft and directly below the primary forming-roll D is a feedwheel M, the periphery of which stands in the plane of the bed of the machine. For= ward of the former D and parallel with it is a finishing-roll N, and directly below this roll and standing at right angles thereto and on opposite sides of the bed are tongue-andgrooved rollers O O, mounted in carriages P, which are adjustably secured to blocks P, which in turn are held in the bearing-blocks O by vertical wings P entering corresponding grooves in the said blocks 0. One of the wings in each of the blocks P is formed with a vertical opening screw threaded for engagement with a screw P which screws are mounted in the bottom of the blocks 0, in which they are held against vertical movement, but free to be rotated, and so that as the said screws are turned the blocks P may be raised or lowered, and with them the carriages P, whereby the positions of the rollers O O are adjusted. Between the forming-roll D and the finishing-roll N is a presser-foot Q, comprising a triangular portion which projects rearward toward the primary roll D and is Vertically adjustable, so that the foot may bear upon the strip fed through the machine and hold the same firmly upon the bed between the primary and finishing rolls. The presserset-screws Q. Upon the bed B are parallel guides R R, leading up to the primary roll D. These guides are adjustably secured to the bed and comprise walls S S, corresponding in height to the thickness of the strip to be covered, and upon their upper surface are profoot is adj ustably secured to the blocks O by vided with flanges T T, corresponding in location to the width of the strip of metal'employed. Upon the forward table 13 are transversely-adjustable guides U U, corresponding in location to the width of the covered strip and so as to guide the same as it is delivered from the rolls.

The strip to be coveredis placed upon the table B and between the walls S S of the guides, as clearly shown in Fig. 5, in which V represents the strip, W the tongue, and Y the groove thereof, and a strip of metal Z of proper width placed upon it and so as to stand between the flanges T T. The strip and sheet of metal are advanced together and passed between the primary roll D and the feed-roll M, the surface of the said roll being roughened, so as to bite into the under surface of the strip. As the strips of wood and metal ad vance the edges of the roll D turn the edges of the metal downward and at the same time bend it over the upper surface of the tongue W, as shown in Fig. 6. The two strips thus partially connected pass below the presserfoot Q, which firmly holds the metal down upon the surface of the wooden strip, and from beneath this foot they advance beneath the finishing-roll N, which corresponds to the upper surface of the strip, and at the same time the edges of the metal are turned by the rolls 0 0' around the tongue IV and into the groove Y. From these rolls the strip advances onto the table B, upon which it is held against lateral motion by the guides U U, which, as before stated, correspond in distance from each other to the width of the finished strip. It will thus be seen that if the strips of wood and metal are started together they will be automatically fed between the rolls and the metal closely folded over the upper surfaces of the wood.

If surface ornamentation, such as ribs or grooves, is desired in the face of the finished strip, either the primary roll D, finishing-roll N,or both,willbe formed with suitable grooves or projections to produce the desired effect.

The distance between the bearings for the primary roll D is sufficient to permit rolls of different Widths to be inserted, and as the tongue-and-grooved rolls are mounted in adj ustable carriages it is readily seen that the machine can be easily changed to cover strips of wood of diiferent widths.

Having fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. In a machine for covering wood with metal, the combination with the bed, of a forming-roll mounted above it, a feed-roll below the forming-roll and means for driving them, a finishing-roll forward of the formingroll and horizontally-arranged tongue-andgrooved rolls arranged respectively on oppo= site sides of but in a plane below said finishing-roll, substantially as described.

2. In a machine for covering wood with metal, the combination with the bed, of a forming-roll mounted above it, a feed-roll below the forming-roll and means for driving them, a finishing-roll forward of the formingroll, and horizontally-arranged tongue-andgrooved rolls adjacent to and on opposite sides of said finishing-roll, and a presser-foot between the forming and finishing rolls, and adapted to bear upon the surface of the strip passed beneath them, substantially as described.

3. In a machine for covering wood with metal, the combination with the bed, of a forming-roll mounted above it, a feed-roll below the forming-roll, and means for driving them, a finishing-roll forward of the form= ing-roll, horizontally arranged tongue andgrooved rolls adjacent to and on opposite sides of said finishing-roll, said tongue-and-grooved rolls mounted in transversely-adj ustable bear= ings, a presser-foot between the said forming and finishing rolls, and vertically adjustable with relation to the surface of the bed, and so as to bear upon the surface of a strip passed beneath said rolls, substantially as described.

4. In a machine for covering wood with metal, the combination with the bed having 4 parallel guides of bearing-blocks mounted on opposite sides of said bed, a forming-roll mounted above the bed in said blocks, a feedroll beneath said forming-roll, and means for driving them, horizontallyarranged tongueand-grooved rolls adjustably mounted in said bearing-blocks upon opposite sides of the bed and forward of the forming-roll, and a presser-foot adjustably secured to said bearing blocks, and so as to stand above the face of i the bed and in advance of the forming-roll,

substantially as described.

5. In a machine for covering wood with metal, the combination with the bed, of a forming-roll mounted above it, a feed-roll below the forming-roll and means for driving them, a finishing-roll forward of the formingroll and horizontally-arranged tongue-andgrooved rolls adjacent to and on opposite sides of said finishing-roll, guides in rear of said forming-roll and adapted to present the strip of wood and metal to the forming-roll, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscrib-.

ing witnesses.
